1 Claim.

The present invention relates to boxes of a class generally known as set up boxes which are usually distinguished from folding boxes in that they are usually composed of heavy paper board which is non-bendable. Set up boxes are generally employed where rigidity and strength of the box is required for packing, shipping and displaying merchandise of a comparatively heavy weight. The invention relates to certain features of construction which makes the box especially suitable for packaging cigars, although it is understood that the invention may be applied to boxes useful for packing merchandise of other kinds.

An object of this invention is to provide a box of great strength and rigidity, which may be produced in quantities by means of automatic machinery at low cost.

In carrying out the invention, the material preferably employed is corrugated paper board composed of outer lamina or sheets between which a corrugated filler sheet is placed. The corrugated board gives the box the required rigidity and produces a box which is lighter in weight than boxes made of solid paper board.

The improved box will be described hereinafter with reference to the accompanying drawings, wherein- Figure 1 is a perspective view showing the improved cigar box complete and in the open position;

Figure 2 is an enlarged transverse sectional view of the cigar box;

Figure 3 is a plan view of the blank of which the body of the improved box is composed; and

Figure 4 is a plan view of a folding blank which provides a lining for the box body.

The body of the box is formed from the blank A of corrugated board which is divided into sections comprising, main section 1 which forms the bottom of the box body, and. sections 2-2 and 3-3 connected to said main section 1 forming respectively the side and end walls of the box body. The outer edges of sections 2 and 3, which form the top edges of the box when assembled, are cut square as shown at 4. The other free edges 5 are beveled so that when the sections 2 and 3 are brought together a mitred comer joint is obtained. Grooves 6 are cut between the bottom section 1 and the side and end wall sections 2 and 3. These cuts are preferably V-shaped so as to permit the folding of the sections and present an uncut outer lamina '7. The blank is cut from the stock so that the corrugations will run across the blank at an angle of approximately 45 degrees, as represented by the dotted lines 8 in Figure 3. With this arrangement the corrugations at the cut edges 5 and the edges of the grooves 6 are all cut diagonally across the grain of the material.

The corrugated board used forv making the blank A is composed of an inner and an outer laminae '7 of paper board with an interposed corrugated sheet. The outer lamina 7 is preferably of a tough strong material which will take printing or decoration nicely, particularly when the printing is to represent wood.

In setting up the box, the sections 2 and 3 are folded at right angles to the bottom section 1 and corner stays or binding strips 9 then applied to hold the sections together. Other binding strips 10 are afllxed in the usual manner to cover and finish the edges of the box all around.

It is customary in making cigar boxes, to extend the end walls above the front and rear walls as shown at 11 to provide a recess 12 which receives the cover 13 hinged to the box body. When the cover is closed the top surface thereof is flush with the top edge of the side walls, providing a tight closure which may be conveniently sealed.

A lining is provided for the box body formed from the blank B shown in Figure 4. Blank B is made of bendable paper board scored to form a bottom section 14 and side and end sections 15 and 16 connected to section 14. These sections form a lining or inner wall for the bottom, sides and ends of the box body, which improves the appearance and generally reinforces the box. In applying the lining, the sections are folded so that the coated surface of the lining is on the inside. Tongues 17 are provided which are folded against the back of the sections 16. Covering flaps 18 are then folded on line 19 over the tongues 17. The side sections 15 are also provided with folding flaps 20 which fold outwardly on the scored line 21. The top edges of the lining are thus reinforced to form a rigid seat for the cover. Any pressure on the closed cover is taken up by the reinforced edge so that the pressure is not imparted to the contents of the box. The reinforced ends 18 provide a rigid seat for the ends of the cover, which is believed to be a novel feature of the box as above constructed.

-Various other modifications may be made in carrying out the constructional details of the invention or in the application of the same other than hereinbefore described and it is therefore to be understood any modification coming fairly within the terms of the appended claim shall be covered thereby.

end folded against the back of the end sections, said end sections having flaps folding outwardly over said tongues whereby said inner member is retained in the folded position and the end walls of said member are reinforced to provide a rigid seat for a box cover.
